(PhysOrg.com) -- According to a new study published in Animal Behaviour, a male black widow spider is able to identify a female spider that has eaten well by simply taking a few steps on the web she spins. Finding a well-fed female seems to minimize their risk of being eaten after mating, a behavior that gave the spider its name.
